New media environments’ comparative effects upon intercultural sensitivity: A five-dimensional analysis     

Amy Jo Coffey  Rasha Kamhawi  Paul Fishwick  Julie Henderson 《Int J Intercult Relat》2013

An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life^®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness.  相似文献   

Forensic child sexual abuse evaluations: assessing subjectivity and bias in professional judgements     

Everson MD  Sandoval JM 《Child abuse & neglect》2011,35(4):287-298

Objectives

Evaluators examining the same evidence often arrive at substantially different conclusions in forensic assessments of child sexual abuse (CSA). This study attempts to identify and quantify subjective factors that contribute to such disagreements so that interventions can be devised to improve the reliability of case decisions.

Methods

Participants included 1106 professionals in the field of child maltreatment representing a range of professional positions or job titles and years of experience. Each completed the Child Forensic Attitude Scale (CFAS), a 28-item survey assessing 3 forensic attitudes believed to influence professional judgments about CSA allegations: emphasis-on-sensitivity (i.e., a focus on minimizing false negatives or errors of undercalling abuse); emphasis-on-specificity (i.e., a focus on minimizing false positives or errors of overcalling abuse); and skepticism toward child and adolescent reports of CSA. A subset of 605 professionals also participated in 1 of 3 diverse decision exercises to assess the influence of the 3 forensic attitudes on ratings of case credibility.

Results

Exploratory factor analysis identified 4 factors or attitude subscales that corresponded closely with the original CFAS scales: 2 subscales for emphasis-on-sensitivity and 1 each for emphasis-on-specificity and skepticism. Attitude subscale scores differed significantly by sample source (in-state trainings vs. national conferences), gender, years of experience, and professional position, with Child Protective Service workers unexpectedly more concerned about overcalling abuse and more skeptical of child disclosures than other professionals—a pattern of scores associated with an increased probability of disbelieving CSA allegations. The 3 decision exercises offered validation of the attitude subscales as predictors of professional ratings of case credibility, with adjusted R²s for the three exercises ranging from .06 to .24, suggesting highly variable effect sizes.

Conclusions

Evaluator disagreements about CSA allegations can be explained, in part, by individual differences in 3 attitudes related to forensic decision-making: emphasis-on-sensitivity, emphasis-on-specificity, and skepticism toward child reports of abuse. These attitudes operate as predispositions or biases toward viewing CSA allegations as likely true or likely false. Several strategies for curbing the influence of subjective factors are highlighted including self-awareness of personal biases and team approaches to assessment.  相似文献   

Measuring scientific contributions with modified fractional counting     

Gunnar Sivertsen  Ronald Rousseau  Lin Zhang 《Journal of Informetrics》2019,13(2):679-694

We develop and propose a new counting method at the aggregate level for contributions to scientific publications called modified fractional counting (MFC). We show that, compared to traditional complete-normalized fractional counting, it eliminates the extreme differences in contributions over time that otherwise occur between scientists that mainly publish alone or in small groups and those that publish with large groups of co-authors. As an extra benefit we find that scientists in different areas of research turn out to have comparable average contributions to scientific articles. We test the method on scientists at Norway’s largest universities and find that, at an aggregate level, it indeed supports comparability across different co-authorship practices as well as between areas of research. MFC is thereby useful whenever the research output from institutions with different research profiles are compared, as e.g., in the Leiden Ranking. Finally, as MFC is actually a family of indicators, depending on a sensitivity parameter, it can be adapted to the circumstances.  相似文献

新疆伊犁新垦区土地荒漠化敏感性评价   总被引：2，自引：0，他引：2  

康蕾  张红旗 《资源科学》2012,34(5):896-902

基于野外调查构建了伊犁新垦区土地荒漠化敏感性的评价指标体系,并在GIS支持下完成了研究区土地荒漠化敏感性综合评价。结果表明：伊犁新垦区超过70％的土地呈现出不同程度的荒漠化敏感性,其中以具有轻度敏感性的荒漠化土地为主,占到新垦区土地总面积的一半以上;中度敏感和高度敏感的荒漠化土地比重分别为14_31％和6．90％。从土地荒漠化敏感性的类型及空间分布来看,南岸大渠灌区的土地主要受水蚀荒漠化影响,近80％的土地具有荒漠化敏感性,高度敏感的荒漠化土地比重超过10％;伊犁河北岸灌区是新垦区内沙质荒漠化敏感性程度最高的区域,超过70％的土地受到荒漠化威胁;察布查尔县伊犁河灌区和团结灌区主要受土壤次生盐渍化的影响,具有轻度荒漠化敏感的土地比重均超过60％;跃进灌区不具有荒漠化敏感性的土地比重达58．28％,环境相对较好,主要分布有轻度敏感的荒漠化土地。  相似文献
